C# Part

public static RoutedUICommand ClearCommand { get; private set; }

static CustomControl()
{
    DefaultStyleKeyProperty.OverrideMetadata(typeof(CustomControl), new FrameworkPropertyMetadata(typeof(CustomControl)));
    CustomControl.ClearCommand = new RoutedUICommand();
    CommandBinding ClearCommandBinding=new CommandBinding(CustomControl.ClearCommand,CustomControl.ClearText);
    CommandManager.RegisterClassCommandBinding(typeof(CustomControl), ClearCommandBinding);
}

private static void ClearText(object sender, ExecutedRoutedEventArgs e)
{
    ...
}

    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="local:LabelEditCtrl">
